Aerosol Device Airflow Selection Mechanism for Multi-Consumable Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol-generating devices lack the ability to efficiently switch between different consumables, such as liquids and tobacco materials, for varied user experiences without requiring manual adjustment or separate devices.
Innovation Solution
An aerosol-generating device with multiple receiving chambers and a selection member that allows airflow to be directed through one chamber while blocking the others, enabling the use of multiple consumables, including heatable and non-heatable options, and allowing for sequential or parallel airflow through different consumables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple receiving chambers are provided for different consumables, then the versatility and adaptability of the device is improved, but the device complexity increases due to the need for multiple chambers and airflow control mechanisms
Solution Approach 1:
The device housing is segmented into multiple receiving chambers (first receiving chamber, second receiving chamber, and optionally third receiving chamber), each capable of accommodating different consumables. This segmentation allows the device to handle multiple consumable types simultaneously while maintaining organized, separate storage and airflow paths for each consumable type.
Solution Approach 2:
The selection member is designed to be movable between different positions (first position, second position, and optionally third position), dynamically changing the airflow configuration. When the selection member moves to different positions, it selectively opens or closes airflow passageways to different receiving chambers, enabling the device to adapt its functionality based on the user's consumption preference without requiring manual disassembly or reconfiguration.
2Ease of operation
If a selection member is used to control airflow between chambers, then the ease of operation is improved, but the device complexity increases due to additional moving parts and control mechanisms
Solution Approach 1:
The selection member serves multiple functions simultaneously: it acts as a valve to control airflow direction, a selector to choose between different consumables, and a mechanical linkage to coordinate the opening and closing of different airflow passageways. This multi-functionality reduces the need for separate control mechanisms for each receiving chamber, simplifying the overall control system while maintaining ease of operation.
Solution Approach 2:
The selection member acts as an intermediary element between the user's input (selecting a position) and the airflow system (directing air to specific chambers). By providing a single, unified control interface that mediates between the user's choice and the complex internal airflow network, the device achieves ease of operation without requiring the user to understand or manually configure multiple separate control mechanisms.
3Device complexity
If the mouthpiece covers multiple receiving openings, then the device structure is simplified, but the ability to selectively access different chambers is reduced
Solution Approach 1:
The mouthpiece is designed with dynamic selective access: it includes multiple receiving openings (first receiving opening, second receiving opening) that are all covered when the mouthpiece is in a neutral position, but can selectively expose specific openings when the selection member is positioned appropriately. This dynamic configuration allows the simplified mouthpiece structure to maintain selective access capability through coordinated movement with the selection member.
Solution Approach 2:
The mouthpiece combines multiple receiving openings and covering functions into a single integrated component. Rather than having separate access mechanisms for each receiving chamber, the mouthpiece merges all access points into one unified structure that can be collectively controlled by the selection member, simplifying the overall device structure while preserving selective access through the selection member's positioning.

Enables users to easily switch between different consumables, such as flavor-based and nicotine-based experiences, by controlling airflow through the device's chambers, optimizing the use of consumables and providing a versatile vaping experience without the need for multiple devices.
Implementation Method 1
the first receiving chamber including the heating element for heating the aerosol-forming liquid
Implementation Method 2
the selection member establishes a first airflow passageway that traverses through the first receiving chamber

AI summary
The method includes establishing a housing defining chambers, the chambers including a first chamber and a second chamber, each of the chambers being configured to accept a consumable, and configuring a mouthpiece to be selectively connected to the housing on an end of the chambers in at least a first position or a second position, the first position aligning an inlet opening of the mouthpiece to direct at least one first airflow in a first direction through the first chamber and in a second direction through the second chamber, the second position aligning the inlet opening of the mouthpiece to direct the at least one first airflow in the first direction through the second chamber and in the second direction through the first chamber, the first direction and the second direction being substantially opposite directions.
